Mooster, so you'll be flying when you're 27+6 ? Then surely by their own rules you can fly without a letter? I think they'd be on very rocky ground legally if they refused, especially if it's worded "after your 28th week" as you could claim that you have a week and one day left to travel without sign off. If you can't see your GP, I think I'd just risk it. You can always wave your notes at them to prove you're not quite 28 weeks yet.
I've started getting proper SPD pains now. :( Thankfully only when I first go to bed, or when I've been sat at my desk for a long time. I will be taking in more cushions for work tomorrow, and walking about a bit more. At least my back is still fairly happy, thanks to these bump bands. :)
As for buying things, so far I have bought the new mattress for the moses basket, and a very cheap changing mat as the old one disintegrated. Just need to buy more muslin squares, and some nappies, and we'll be done for shopping. Now I just need to fix the wall and floor in the new bedroom, get it safe for habitation, decorate, furnish, move in DD1, pull all DD1's baby stuff out of storage, clean it up, and we'll be finished! So we're no where near nearly there!
